Product Overview


  • Potassium & Magnesium Aspartate
  • Dietary Supplement

Source Naturals uses extremely high quality potassium and magnesium aspartate. K-Mag Aspartate is an excellent source of energizing nutrition for athletic activity or fast-paced daily living. Potassium is essential for nerve function, muscle strength, and glycogen formation, among other biochemical processes.

Magnesium plays a key role in over 300 enzymatic reactions, including those involved in the Krebs cycle (the body's main energy production processes), the relaxation of muscle tissue, neurotransmitter activity and hormone regulation. L-Aspartic acid also plays a vital role in energy production and is a major excitatory neurotransmitter.

Suggested Use

1 to 3 tablets daily with a meal.

Other Ingredients

Stearic acid, modified cellulose gum, colloidal silicon dioxide, and magnesium stearate.

Removed with L-ornithine what I suspected to be ammonia in the brain

Posted by Prevaileth on May 01, 2015 | Verified Purchase

This product seems to work effectively along with L-Ornithine at removing ammonia build up in the brain. I felt immediate relief - I could actually feel the liquid build up in my brain and it was going no where. It only seemed that L-ornithine taken on itself was pushing it somewhere, but taken with aspartate it felt like all that liquid build up was relieved (overnight as I take it before bed). And it helped me sleep easier to boot. There is no UREA cycle in the brain, so you must supplement to remove or else live with it for the rest of your life. I suffered mental fatigue and cognitive impairment for years, after a bout of drinking "ionised" water. I also had a bad liver at the time. Ionised water is known to exacerbate liver issues (the booklet said don't drink if you have liver problems), and as a result I believe I suffered with ammonia build up.

Great product

This is a great product for the price. This formula is over looked by more expensive products. The tablets are a little rough, but it's not as bad as country life's magnesium tabs I've had in the past. Similar to the OG formula XCell R8 which is not being produced anymore.

Seems to Work

Posted by Reviewer1826883 on Jan 21, 2014 | Verified Purchase

I use this product to regulate heart beat and it seems to work. I was recommended to take Magnesium Aspartate by the cardiologist and this seems to be the closest I can get and it does the trick.
